+    Horrendous workaround
+
+    To unequp items, the java side uses WornItems.setItem, which has
+    a check for multiItem. Basically, if it's active, it won't actually remove the item,
+    fucking things up. So, to be 100% sure that we're removing the items, we're gonna
+    disable and re-enable the multi-item bool for the Unequip Action.
